I really like the purple for the map screen, and also, I like how the cave map looks realistic. Not realistic, but... it has a waterfall, it's actually proportional, overall nice job with that. But one thing though, the shrine graphics look weird with that red outline on them =/
I've already ficed all the shrine's red outlines. As for the ice cave, the background palette has been changed since those shots were taken:
The other was too blue-green for an icy feel.
OW Mario will be changed eventually. I'm currently working on the bonus room of level 4. FPI allowed me to use the graphics for his bonus rooms for the game as long as he gets credit. I can show you guys when it's done.
Like turn the greenish to lightblue? I tried that and wasn't too satisfied. I could try it but don't expect a change. I rather like it myself. It's like even though it's a freezing cold place, life still manages to grow.
Like... I guess turn the blue part about the slightest bit brighter? It kind of just looks water logged the way it is. But the green I think would look fine left alone, although might be edited to match if you do edit the blue on the ground.
